That's not what I meant at all.Lightknight said:The US has the lion's share of available research data. If you want me to run the numbers by another country or region then that region will have to start producing more research to make comparisons simpler. Europe is the closest to the US in availability of research but that's more segregated by country rather than landmass. Since America also has a ton of farmland and a significant agricultural footprint it makes it a rather convenient place to compare items.
If you can explain why the US market isn't a valid landmass to compare products then I would be glad to adjust my approach to the issue. But believe it or not, 1 kg of carbon emissions in the US is the same as 1 kg of carbon emissions produced wherever you're from. So I'm having a hard time believing that the CO2 "standards" of relative countries have anything to do with the discussion at hand.
For many products, transport takes up a good amount of the carbon footprint, right? It's not just the transport of the product itself, but also everything that is needed to make that product (animal feed for lifestock, for instance). From an ecological view point, is makes sense to try to limit transportation, meaning the most ecological diets are the ones that are (almost) naturally supported by the region the person lives in. For instance, eating fish makes sense if you live in a region near the ocean or another large water source. It does not make sense if you live in one of the dry parts near the middle of the continent. So of course having some generic guidelines for the whole country wouldn't be ideal ecologically speaking. Just taking those guidelines and saying it would be worse for the environment if everyone followed them is a rather silly argument, because of course it would be worse!
There's this type of bean I like that I eat frequently. They're grown in the (rather small) country where I live and I can't even find an English name for it. It has a fairly low carbon foodprint. For me anyway, as the plant does well in this climate and there's not much transportation involved. However, if you were to start eating it, you might leave a much bigger footprint, as your location may be less suitable or you may have to import it. So in a way, carbon footprints are relative.
